Work Text:
Gen is late again coming home from work.
Senku had used the opportunity to work late again because Gen wouldn't be able to tell him off. Course even if he was here to tell him off, he would still be working because A. Doing the exact opposite of what Gen said was hilarious and B. He really needed to finish the project he was working on. He had stayed up the last 4 days and would probably stay up tonight too.
He starts to get a little worried though when it hits 1 am and Gen still isn't back. He's just about to call him when he hears keys jingling in their door and someone stumbles through it.
From his lab he hears Gen sigh and kick off his shoes. He goes upstairs to take a shower Senku guesses but then he comes down again later to check on him.
“You’re late, mentalist.” Senku comments, not looking up from his work, as he walks in.
“You’re up late too.”
Senku hums in response and Gen just watches him continue to work diligently despite the heavy bags under his eyes. "Do you ever sleep?"
"Sometimes I blink." he deadpans.
"And?"
"From just blinking alone, humans spend around 3 hours a day with their eyes closed."
Gen huffs "You're so insufferable sometimes. Surely you should know also that going for extended periods without actual sleep affects humans too?"
"Need to finish this, can't sleep yet."
"Even if it kills you?"
"Yup"
"Even if I ask you too?"
"Yup"
Gen sighs. "Why won't you listen to me?"
"It's my job."
"Science or ignoring me?"
"Both" he grins.
Gen rolls his eyes. "Alright then, Senku dear, can I at least make you some tea?"
"Aren't you tired?"
"It's no problem, dear."
"...okay."
He leaves to do just that, Senku hears clanging in the kitchen before Gen comes back with some tea. "Here you go."
"Thanks"
They both continue talking for a little while he drinks the tea.
"I think I'll head to bed now, dear."
The scientist just waves him off and continues with his equations.
He hears Gen walking up stairs to the bedroom when he hears him scream. He rushes upstairs to check on him. "What's up? Are you okay?!"
"Yeah yeah… There's just a spider on the bed." He points to the far corner.
Senku rolls his eyes. "Are you kidding me?"
"Please~ get it. I'll go get a cup and paper." And before Senku can argue he's left to go downstairs.
He sighs and climbs on top of the bed, he stretches over it to find the spider
Only…
"Wait a minute, there is no-"
He suddenly feels arms wrapping around waist from behind and a weight pushing him down onto the bed. "Hey?! The hell are you doing?!"
Gen grins and closes his eyes, snuggling into his partner's back, "Sorry dear, but this is for your own good."
"Get off- I left a Bunsen burner on in the lab." He struggles to get out of Gen's grasp, but it is no use. He has to wonder where his scrawny partner got all this strength from. "What if something sets on fire?"
"Then you'll die in my arms, how sweet~"
"Ugh, gross. I'm not even tire-" a yawn escapes from his mouth just then.
Gen opens his eyes a little and smirks. "What was that?"
Senku suddenly feels so warm and comfy here he could almost- "Why…why do I feel so …sleepy" he yawns again
"I may have slipped a little chamomile into your tea, my dear~"
Senku would have smacked his forehead for being so stupid and drinking that tea if Gens arms weren't wrapped tightly around him. He shakes his head trying to keep himself awake. "Doesn't matter, I'll just wait for you to go to sleep and go back to work."
"I locked the door to your lab and hid the keys when I went down just now. Oh, and I did shut off the Bunsen burner. So, you can relax and finally sleep~"
"Fucking asshole," Senku murmurs into a pillow. “Using your mentalist tricks against me."
"That was a really obvious trick you fell for, which shows how tired you are." Gen loosens his grip on Senku when he feels him relax a little, still hugging him though.
"It's you and your damn comfy arms, mentalist …" he closes his eyes.
"It's your own fault I have to resort to such tactics, Senku dear. You don't take care of yourself, so I'll have to do it for you."
"I'll get you back, ten billion percent I'll get you back."
Gen hums in response
"...Thank you though" he whispers quietly, slipping into unconsciousness fast. He hears Gen giggling behind him and smiles before fully falling asleep.
…
Gen groans as his alarm goes off, it's loud and annoying, though he supposes that was the whole point of an alarm.
He moves his right arm to find his phone but it is trapped under something, so he moves his left arm instead and feels around for it. When he finally finds it, he groggily opens one eye to turn off the alarm and check the time.
7:00 am
45 minutes before he was supposed to be at work.
Gen's eyes close again and his arm falls to their side. He really didn't want to go and stay into the late hours of the night today, but he had an important show.
And he would be late if he stayed in bed too long, so he forces his eyes open.
He then sees the reason he couldn't move his arm was because Senku was latched onto his side like a koala bear, hugging him tight like he would disappear if he let go.
It takes basically every piece of will power Gen has not to squeal with how adorable he looks like that. He doesn't wanna wake him up just yet so instead what he does do, is reach for his phone with his free arm again to take a bunch of pictures which he would tease the scientist with later when he was more awake.
After taking an ungodly number of photos, he quickly puts the phone away when Senku shifts slightly. He scrunches his eyes a little bit and rubs them cutely and Gen thinks he might die just from this.
"Mentalist?" He lifts his head a little.
"Yes dear?"
"Why are you up, you're usually able to sleep through a hurricane."
"Oh yeah?'
"Yeah, usually it takes me putting vinegar next to your nose to get you up."
"I hate it when you do that."
Senku hums in response. "So why are you u- oh yeah." He groans and his head drops back onto Gen's chest.
"Finally remember who makes the money for your experiments?" Gen chuckles.
Senku doesn't respond and Gen thinks he might have fallen asleep again when. "Are you about to get up?"
"That was the plan so- Oh." Senku tightens his arms around him and slings one of his legs over him too.
"Hell no, not after the shit you pulled last night."
"Senku dear I really need to go-"
"You dragged my ass here so now you're staying here. Plus, it's…"
"Hmm? I didn't catch that."
"...It's better for you to stay."
"Aww." Gen coos and tilts his head to look at his partner before hugging him back more enthusiastically.
"Wha-?!"
"I would love to stay with you dear, but you know I have work."
"I didn't say that… I just meant that you seemed to be really tired recently from work and doing this releases a chemical called oxytocin which relieves stress, lowers blood pressure and-"
"Dear, just admit you want to cuddle."
"Even if I do, you're still gonna leave." He grumbles.
"True, though I would like a day off, I have to go, okay?"
"...Fine. You go to the bathroom first; I'll get up after." Senku finally gets off of Gen who feels really bad for leaving his partner like this but still gets up to go to the bathroom.
He washes his face and brushes his teeth. He goes into the next room and is just about to get changed when he hears Senku talking to someone.
He rushes back to the bedroom to find Senku on his phone.
"-yeah, sorry but he'll probably be better in a couple days though."
"-Uh huh, goodbye."
"The hell did you just do??"
Senku looks up and grins at Gen "I got you that day off you wanted, actually I got 4 of them for you."
"Ugh," Gen rubs his temples. "My manager is gonna give me such an earful for getting 'sick' you know."
"Well now you got nothing better to do so might as well come back to bed." He declares proudly, patting the space next to him.
Gen sighs "You're such a pain, you know. Why am I with you again?" Despite his words, he lays down again.
Senku lays down and curls into him. "Dunno, you should have thought of that when you confessed to me."
"You're the one who said, 'Asagiri Gen would you like to be my partner in crime.'" Gen points out as he pulls Senku even closer into his chest.
"It just made logical sense; you wanted me romantically and I wanted someone to torment with my antics. And the mentalist must have been off his game that day because he actually accepted."
"Indeed" Gen sighs "Biggest mistake of life."
"You love me though." Senku mumbles.
“I do.” he hums.
“I love you too.”
Gen's eyes open and he looks down at Senku who’s fallen asleep by now. He smiles fondly at him and brushes back some of Senku's hair back so he can place a kiss on his forehead. After a while he falls asleep too and they both stay like that, safe in each other's arms, till the late hours of the afternoon.
